Twickenham MP Dr Tania Mathias has revealed that RFU chief Ian Ritchie has guaranteed Chelsea will not be allowed to play at the home of rugby, reports the London Evening Standard.
Twickenham had been earmarked as a possible temporary home for the club while Stamford Bridge is being redeveloped.
Twickenham residents have been opposed to Chelsea moving to the rugby venue since the club announced plans to rebuild Stamford Bridge.
And in a letter sent to Ritchie last week following Hammersmith and Fulham's decision to give Chelsea the green light, she wrote: "Following the decision by Hammersmith and Fulham council to approve plans for Chelsea's new stadium, I am writing to you to re-state my position that I do not support Chelsea FC being based, temporarily or otherwise, at Twickenham.
"My opposition to more non-rugby fixtures at Twickenham is based on concerns regarding increased problems for local residents such as match-day traffic, an increase in litter, public urination and other anti-social behaviour. I will be meeting with the Borough commander, Parm Sandhu, to discuss my concerns.
"I would appreciate reassurance from yourself that my fears are unfounded, as hosting regular football matches at the RFU Stadium is clearly the wrong decision for Twickenham."
Ritchie has already replied to Mathias and stated that "there is no intention to host regular football matches at Twickenham".
